Discussed are a display device with an integrated touch screen and a method of operating the same. The display device according to an embodiment includes a display panel including a plurality of pixel electrodes; a touch screen including m number of electrodes which are formed to overlap with the plurality of pixel electrodes, wherein m is a multiple of n, and n is an integer equal to or greater than two, and wherein the m electrodes are divided into n number of electrode groups; a touch driver configured to generate a touch scan signal and to supply the generated touch scan signal to a display driver; and the display driver configured to apply a common voltage or the touch scan signal to one or more of the m electrodes depending on a driving mode of the display device.

Display device with integrated touch screen and method for driving the same

The present disclosure provides a touch sensing device, a touch sensing circuit, a data driving circuit, and a display device driving method, which make it possible to activate different sensing areas according to a finger mode and a hover mode, and which activate as many sensing areas as possible simultaneously in a hover mode, which means sensing driving in the case of non-contact with regard to sensing areas, thereby enhancing sensing sensitivity, and improving sensing detection performance even in the hover mode.
